Maintenance
To clean the tape heads and tape
path
Contaminated tape heads cause poor
recording or sound drop-out in playback.
We recommend cleaning after every 10
hours of operation.
Open the tape compartment and wipe the
heads, the pinch rollers and the capstans
with a cleaning swab slightly moistened
with cleaning fluid or alcohol. Wipe the
parts shown below.

Playback head
Deck B
Cleaning swab
Erase head
Record/playback head
Insert a tape when the areas cleaned are
completely dry.
To demagnetize the tape heads
After 20 to 30 hours of use, enough residual
magnetism will have built up on the heads
to begin to cause loss of high frequencies
and hiss. At this time, demagnetize the
heads and all metal parts in the tape path
with a commercially available tape head
demagnetizer. Refer to the instructions of
the demagnetizer.
To clean the cabinet
Use a soft cloth slightly moistened with
mild detergent solution.
To clean the CD
When a CD is dirty, clean it with a cleaning
cloth. Wipe the CD from the centre out.
Notes on CD
•Do not use solvents such as benzene,
thinner, commercially available cleaners,
or anti-static spray intended for vinyl LPs.
•If there is a scratch, dirt or fingerprints on
the CD, it may cause a tracking error.
